Landforms (their development, size, shape, etc.) are the subject of investigation in the field of geomorphology, which has developed as a branch of geology. Geomorphology seeks to systematically describe and order the forms of the earth surface (i.e., landforms) and to understand the reasons and processes behind their formation and evolution. Geomorphology assumes that landforms are not immutable, but that all landforms develop and transform more slowly or more quickly.
To better understand and predict landforms and their development, it is important to have as much data as possible about them. With the help of remote sensing techniques and data (i.e. satellite images mapping landforms from a birds’ eye perspective), landforms and their changes can be detected and analyzed. However, it is difficult to study landforms and their changes only on the basis of satellite imagery. To verify the knowledge gained from remote sensing data, data collected directly in the field is needed. Here the support of citizens is essential: the reporting of landforms, their location, and photos of them will allow scientists to review and improve knowledge gained through remote sensing.
